Bottle-Top Dispenser Features

The Hawach Bottle-Top Dispenser is designed to meet the most stringent purity requirements in trace analysis. Special cleaning steps, and practical application verification before trace analysis, to meet stringent non-polluting operating conditions. The raw materials used in the parts in contact with the medium are a variety of fluoroplastics. The release of trace metal content is controlled below the ppb level and can be controlled in the ppt range depending on the application. Excellent chemical resistance, especially for corrosive media, such as high concentrations of acid and alkali, hydrogen peroxide, hydrofluoric acid, and bromine modular structure is easy to disassemble, easy to clean, or replace the distribution pipe.

It is suitable for the direct removal of corrosive reagents from bottles, including concentrated acids such as H3PO4, and H2SO4, bases such as NaOH, and KOH, salt solutions, and many organic solvents.
